Chrysanthemum plant named ‘Zanmugolmine’

ABSTRACT

A  chrysanthemum  plant named ‘Zanmugolmine’ characterized by its medium sized blooms with yellow ray florets and prolific branching; natural season flower date August 17 (week 34); blooming for a period of 5 weeks.

Botanical designation: Chrysanthemum×morifolium Ramat.

Cultivar denomination: ‘Zanmugolmine’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofchrysanthemum plant, botanically known as Chrysanthemum×morifoliumRamat., commercially known as a garden mum, and hereinafter referred toby the cultivar denomination ‘Zanmugolmine’. ‘Zanmugolmine’ is a productof a breeding and selection program for outdoor pot mums (garden mums)which had the objective of creating new cultivars with a double typeinflorescence, a natural season flower date around August 17 (week 34),blooming for a period of 5 weeks. ‘Zanmugolmine’ is a seedling resultingfrom a cross of the female parent id 19268 with the male parent id15038. Plants of the new cultivar ‘Zanmugolmine’ differ from plants ofthe female parent in the color of the ray-florets. The color is in theseedling yellow, while pink in the female parent.

Plants of the new cultivar ‘Zanmugolmine’ differ from plants of the maleparent in the following characteristics. (1) Natural season floweringdate. And (2) Inflorescence size. (1) Plants of the seedling flowerearlier in the season than those of the male parent. (2). Inflorescencesof the seedling are larger than those of the male parent.

The new and distinct cultivar was discovered and selected as a floweringplant by Wilhelmus Bernardus Blom on a cultivated field in Rijsenhout,The Netherlands in 2005. The first act of asexual production of‘Zanmugolmine’ was accomplished when vegetative cuttings from theinitial selection in 2005 were propagated further in a controlledenvironment in Rijsenhout, The Netherlands. The new cultivar has beenfound to retain its distinctive characteristics through successivepropagations.

BRIEF DESCRIPTION OF THE DRAWINGS

The present invention of a new and distinct variety of chrysanthemum isshown in the accompanying drawings, the color being as nearly true aspossible with color photographs of this type.

FIG. 1 shows a plant of the cultivar in full bloom.

FIG. 2 shows the various stages of bloom of the new cultivar.

FIG. 3 shows the various stages of foliage of the new cultivar.

DESCRIPTION OF THE INVENTION

The observations and measurements were gathered from plants grown outdoor in Rijsenhout, The Netherlands under natural day length andtemperature and planted in week 23 in 2009. The natural blooming date ofthis crop was August 17 (week 34) . The average height of the plants was18 cm. No growth retardants were used. No tests were done on disease orinsect resistance or susceptibility. No tests were done on cold ordrought tolerance. This new variety produces medium sized blooms withyellow ray florets blooming for a period of 5 weeks.

From the cultivars known to inventor the most similar existing cultivarin comparison to ‘Zanmugolmine’ is ‘Zanmustone’ (U.S. Plant Patentapplied). When ‘Zanmustone’ and ‘Zanmugolmine’ are being compared thefollowing difference is noticed: The differences of ‘Zanmustone’ and‘Zanmugolmine’ are (1) Color ray-florets. And (2) Plant size (1) Theray-florets of ‘Zanmugolmine’ are less intensively yellow than those of‘Zanmustone’. (2) The plants of ‘Zanmugolmine’ are slightly smaller thanthose of ‘Zanmustone’.

The following is a description of the plant and characteristics thatdistinguish ‘Zanmugolmine’ as a new and distinct variety.

The color designations are taken from the plant itself. Accordingly, anydiscrepancies between the color designations and the colors depicted inthe photographs are due to photographic tolerances. The color chart usedin this description is: The Royal Horticultural Society Colour Chart,edition 2001.
